for samplesfor liquid nitrogenstorage

Product overview
Static storage BNC-A series biologic liquid nitrogen tanks for long-term static preservation of biological samples.

Summary
The BNC-A static storage series provides compact, cost-effective liquid nitrogen tanks engineered for long-term static storage of cryogenic samples. Constructed from high-strength lightweight aluminum alloy with multi-layer insulation, these models combine low evaporation loss with large internal capacity. Multiple neck sizes, canister configurations and optional accessories allow adaptation to biobank and laboratory workflows.

Biologic Liquid Nitrogen Tank Product Features
